Geriatric Emergency Department Collaborative:
Research Data Warehouse

What is the GEDC Research Data Warehouse?

The Geriatric Emergency Department Collaborative (GEDC) research data warehouse (RDW) is a cloud-based, multi-site research infrastructure supporting patient-centered data for evaluation of interventions and characteristics aimed at providing improved care for older adults in the ED.

Who is it for?

The RDW is currently open to GEDC member sites and their authorized staff ONLY. Only sites that contribute data can conduct analyses within the environment.

How can my GED benefit from the Data Warehouse?

The RDW provides you with a user-friendly dashboard with an on-demand summary of your GED’s key performance indicators (KPIs), and lets you benchmark your metrics to aggregate data from other GEDs around the country. This helps you recognize opportunities for improvement, identify relevant interventions, track trends, report on outcome measures and benchmark your findings. For those interested in multi-site research, it will also facilitate multi-site analysis of patient-level data.

How is the data warehouse different from a registry?

Clinical registries are often used for reporting or reimbursement purposes and not designed to address research questions. The RDW does not provide reporting for reimbursement instead is specifically designed to help your site monitor and track geriatric emergency care initiatives and facilitate research on the impact of geriatric emergency care. This will be done through a secure HIPAA-compliant platform for investigators to access and track trends across a variety of metrics and analyze data.

What kind of data is included and how was it determined?

GEDC members convened to identify key priority areas for investigation in 2017.  An expert workgroup of EM clinicians at that time agreed on initial key metrics to capture. The data warehouse prioritizes information already captured in existing codes such as ICD-10, CPT, and RxNorm, to name a few.

The RDW is considered a limited data set, with the only qualifying personal health information (PHI) being date of service. Initial elements being included: Demographic data (age, sex, race, insurance type); ED census of older adults, ED diagnoses(s), ED length of stay, ED procedures, disposition, medications prescribed, 30-day ED revisit rate, and 30-day readmission rates to the same hospital. 

Please note that prior to providing site data, sites must complete a Data Use Agreement with West Health to enable data sharing, a process which can take a few months.
